Substitution of Fish Meal by Maggot Meal in the Diet of Nile Tilapia Oreochromis niloticus in Male Monosex Breeding

The present study was conducted to evaluate the efficacy of dietary protein from maggot meal to replace fish meal protein in Oreochromis niloticus feed with average weights of 22 4 g. The fish diet (FD) and the commercial diet (CD) were used to compare the maggot diet (MD). The fish were fed twice times daily to duplicate groups at 5-2 % body weight for consecutive 180 days. After this days, fish fed with FD and MD were obtained the highest final weight (FW) (354.31 21.9 g and 325.4 21.19 g respectively) compared to those obtained by CD (284.43 20.11 g). The specific growth rate (SGR), feed utilization and survival rate (SR) shown no significant different (pgreater than 0.05) to on and other diet. The production cost /kg of fish produced was reduce with the use of maggot meal in fish feed by 37.58 % compared to FD. The carcass chemicals composition were evaluated. In conclusion, these results of this study indicate the possibility of completely using maggot meal as a source protein in the diet of Oreochromis niloticus male to increase the growth of fish and reduce the cost of 1 kg of fish produced.
